Wind Power Formula Calculator
Calculate instantaneous power from user-supplied air density, area, speed and coefficient.
A QUICK WALKTHROUGH
How to use this tool
- Enter all values in the stated units.
- P=½ρAV³Cp in watts. ρ>0 in kg/m³, A>0 in m², V≥0 in m/s, 0≤Cp≤1. The uniform steady-flow model uses your coefficient; it includes no weather distribution, turbine curve, electrical losses or time integration. It does not forecast generation or energy yield.
